ComfyUI Node: Fit Size From Image (FS)

Fit Size From Image (FS):

The FS: Fit Size From Image node is designed to help you resize an image while maintaining its aspect ratio, ensuring that the resized image fits within a specified maximum size. This node is particularly useful for AI artists who need to standardize image dimensions for various applications, such as preparing images for model training or ensuring consistency across a dataset. By leveraging this node, you can easily resize images without distorting their proportions, making it a valuable tool for maintaining the visual integrity of your artwork.

Fit Size From Image (FS) Input Parameters:

image

This parameter accepts an image that you want to resize. The image should be in a format that the node can process, such as a tensor representation of an image. The node will use this image as the basis for resizing operations.

max_size

This integer parameter defines the maximum size (in pixels) to which the image should be resized. The default value is 768, and it can be adjusted in steps of 8. This parameter ensures that the resized image's width or height does not exceed the specified maximum size, helping to standardize image dimensions.

upscale

This parameter is a boolean option that determines whether the image should be upscaled if its dimensions are smaller than the specified max_size. The available options are "false" and "true". If set to "false", the image will not be upscaled beyond its original dimensions. If set to "true", the image can be upscaled to fit the max_size.

Fit Size From Image (FS) Output Parameters:

Fit Width

This integer output represents the width of the resized image. It is calculated based on the original image dimensions and the specified max_size, ensuring that the aspect ratio is maintained.

Fit Height

This integer output represents the height of the resized image. Similar to Fit Width, it is calculated to maintain the aspect ratio while fitting within the specified max_size.

Aspect Ratio

This float output represents the aspect ratio of the original image, calculated as the width divided by the height. This value is useful for understanding the proportions of the image and ensuring that they are maintained during resizing.

Fit Size From Image (FS) Usage Tips:

• To maintain the original quality of your image, set the upscale parameter to "false" if you do not want the image to be enlarged beyond its original dimensions.
• Use the max_size parameter to standardize the dimensions of a batch of images, ensuring consistency across your dataset.
• Consider the aspect ratio output to verify that the proportions of your image are preserved after resizing.

Fit Size From Image (FS) Common Errors and Solutions:

Invalid image file: <image_path>

• Explanation: This error occurs when the specified image file cannot be found or is not in a valid format.
• Solution: Ensure that the image file path is correct and that the file is accessible. Verify that the image is in a supported format.

Unsupported image format

• Explanation: This error occurs when the provided image is in a format that the node cannot process.
• Solution: Convert the image to a supported format, such as a tensor representation, before passing it to the node.

Image dimensions exceed maximum allowed size

• Explanation: This error occurs when the image dimensions are larger than the specified max_size and the upscale parameter is set to "false".
• Solution: Increase the max_size parameter or set the upscale parameter to "true" to allow the image to be resized to fit within the specified dimensions.
